Truck Tyre Reef, also called Pistol Point, is the middle of three little-dived walls between Secluded Cemetery and Pistol Crack on the cliff coast north of Cape Banks. The main wall runs north–south with a flat reef top at 18 m and a face dropping to about 22 m, and beyond it the bottom continues out to 25 m and more. Near the anchorage a large rock leans against the wall at an angle to form a distinctive tunnel, and north of it the face carries dense sea squirts, sponges and gorgonians with small overhangs and ledges.

The best section is actually out on the deeper ground: heading east to 25 m and then north brings you over reef carpeted with thousands of small fan-shaped sponges, an unusual sight in Sydney. South of the tunnel the wall swings west and the rock is noticeably cleaner, and it probably continues across a bare patch to Pistol Crack. The name comes from the numerous truck tyres wedged into the reef, relics of the Randwick council rubbish tip that once occupied the cliff top and shed debris into the sea.

Cuttlefish, wobbegongs and moray eels are the regular residents, and black coral has been noted in the deeper sections. As with its neighbours the appeal is untouched reef fifteen minutes from a Botany Bay ramp with nobody else on it; McFadyen calls it a really good site worth diving more often. It is most naturally done as the deep first dive of a private-boat morning, or as the middle leg of the Secluded Cemetery to Pistol Crack drift.

Private boat only. From Botany Bay round Cape Banks and run north about 1.4 km along the cliffs below the cemetery and the old Randwick council tip site; approach from the ocean side and anchor on the GPS mark where the flat 18 m reef top drops to 22 m. About 12–15 minutes from the heads.

No charter operator visits.

Open coast with no shelter but a deep reef top, so diveable in seas up to about 1.5 m; westerly winds are ideal and north-easterlies acceptable in the morning. A mild current from the north is common and can be used for a drift from Secluded Cemetery. Visibility is generally very good along this cliff line, 15–25 m after westerlies; it drops after heavy rain and big southerly swells.

Depth makes bottom time (about 25 minutes) the main constraint.

From the anchor head east to 25 m and then north for about 15 minutes over the better section of reef with the fan sponges, turn west to the main wall and follow it south to the tunnel under the angled rock near the anchor. Look at the cleaner southern wall past the tunnel, then reverse north and ascend at the anchor.

No regular charter – private boat or dive-club (St George Scuba Club) only
